Try this:

Code:

[System.Runtime.InteropServices.DLLImport("PMX.dll")]
private static extern void PostMessageX(IntPtr hWnd , UINT msg, IntPtr wParam, IntPtr lParam);

//Lalaa....
//Later...

System.Diagnostics.Process[] myprocs = System.Diagnostics.Process.GetByName("MyApp"); //I think that's how it is, it's been a little while
IntPtr hWnd = myprocs[0].ID; //First instance of the application

PostMessageX(hWnd,0x09,0,0); //I'm guessing that 0x09 is the message that you want to send

i have tried it but i still get errors =\

Code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;

using System.Windows.Forms;
using System.Runtime.InteropServices;

namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{

[DllImport("PMX.DLL", EntryPoint = "PostMessageX")]
public static extern IntPtr PostMessageX(IntPtr hWnd, int msg, IntPtr wParam, IntPtr lParam);

System.Diagnostics.Process[] myprocs = System.Diagnostics.Process.GetByName("MyApp");
IntPtr hWnd = myprocs[0].ID; //First instance of the application

public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{

PostMessageX(hWnd, 0x41, 0, 0); //I'm guessing that 0x09 is the message that you want to send

}
}
}

myprocs[0].ID is the PROCESS ID, NOT THE WINDOW HANDLE! _________________

shoudnt your PostMessageX look like this?

Code:

private const int WM_KEYDOWN = 0x100;
....

PostMessageX(hWnd, WM_KEYDOWN, 0x41, 0);

My bad, I didn't finish it.

I haven't done this in a while;

API Calls:

Code:

[Flags]
public enum ProcessAccessType
{
PROCESS_TERMINATE = (0x0001),
PROCESS_CREATE_THREAD = (0x0002),
PROCESS_SET_SESSIONID = (0x0004),
PROCESS_VM_OPERATION = (0x0008),
PROCESS_VM_READ = (0x0010),
PROCESS_VM_WRITE = (0x0020),
PROCESS_DUP_HANDLE = (0x0040),
PROCESS_CREATE_PROCESS = (0x0080),
PROCESS_SET_QUOTA = (0x0100),
PROCESS_SET_INFORMATION = (0x0200),
PROCESS_QUERY_INFORMATION = (0x0400)
}

[DllImport("kernel32.dll")]
public static extern IntPtr OpenProcess(UInt32 dwDesiredAccess, Int32 bInheritHandle, UInt32 dwProcessId);

[DllImport("PMX.dll")]
private static extern void PostMessageX(IntPtr hWnd , UINT msg, IntPtr wParam, IntPtr lParam);

Your code:

Code:

System.Diagnostics.Process[] myprocs = System.Diagnostics.Process.GetByName("MyApp"); //I think that's how it is, it's been a little while
IntPtr id= myprocs[0].ID; //First instance of the application
IntPtr hWnd = OpenProcess(ProcessAccessType.Operation, 1, id);

PostMessageX(hWnd, 0x09, 0, 0);

API Calls:

nooo, you don't open the process either, hWnd is a handle to the Window, which you get from the FindWindow API call, not by process handle!

Code:

MSG:UINT;
WPARAM:wParam;
LPARAM:lParam):BOOL;stdcall;
external 'HookHop.dll' name 'PostMessageA';

I think.

Tested hookhop on my bot, works perfectly and the size of the dll is amazingly minimised. _________________

If you look in my DEF file... you will see that the exported name for my "API" is hhPostMessageA. I do not program in C# so I cannot tell you how to import it. _________________
